The Siege of Jadotville is a 2016 historical drama war film directed by Richie Smyth and written by Kevin Brodbin. It was first screened at the 2016 Galway Film Festival.

The film received a limited cinema distribution in Ireland in September 2016, and planned for simultaneous worldwide distribution on Netflix and a number of US iPic Theaters during October 2016.

The film is based on Declan Power's book, The Siege at Jadotville: The Irish Army's Forgotten Battle (2005).

The Siege of Jadotville took place in September 1961, during the United Nations intervention in the Katanga conflict in Congo-Léopoldville, in Central Africa. "A" Company, 35th Battalion (UN service) of the Irish Army ONUC contingent were attacked by Katanga Gendarmerie troops loyal to the Katangese Prime Minister Moise Tshombe.

The lightly armed Irish soldiers, besieged in Jadotville (modern Likasi), resisted Katangese assaults for six days as a relief force of Irish and Swedish troops unsuccessfully attempted to reach the Irish force.

The outnumbered Irish company were eventually forced to surrender after ammunition and supplies were exhausted, but not before inflicting heavy casualties on the Katangese and their mercenaries. They were held as prisoners of war for approximately one month, with no loss of life. It was the last engagement of the United Nations Operation in the Congo (ONUC) peacekeeping mission to use Irish and Swedish troops in hostile action.
